STEAM-SUPPLYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 236,810, dated January18, 1881.

' Application filed November 12, 1880. (No model.)

To all whom it may concern:

Be it known that I, MILTON W. HAZELTON, of the city, county, and StateptNew York, have invented a new and Improved System for Supplying Steamfor Power and Heating Purposes, of which the following is aspecification.

The invention consists in combining with a heating-tank certaininstrumentalities, hereinafter described, for the purpose of supplyingsteam for power or heating purposes.

The drawing represents a front elevation of the device, partly insection.

In the drawing, A represents the central steam-generator or nest ofboilers, that is dedesigned to be filled with water, to the exclusion ofany steam-space.

B is a pipe, designed to be of any desired length, and to be suitablyjacketed to prevent radiation, leading from the top of the generator Ato a reservoir or sub-station, O, which consists of a strong ironcylinder provided with a safety-valve and steam-escape or distributingpipes. The pipe B is provided with suitable regulating cocks or valves aat either end,.for the convenience of the operators in charge of thecentral and sub-stations, and a pump, B, may be used in connection withsaid pipe B, wherever it may be required, to force the hot water fromthe central station, A, to the. sub-stations G. From this reservoir orstation 0 is a return-pipe, I, provided with suitable cocks or valves1), and a pump, G, connecting with the mud-drum H of the centralgenerator or station, A, from which drum H a pipe, I, connects directlywith the said central generator or station, A.

It is designed to fill the generator A and pipe B with water, and alsothe reservoir or sub-station 0, up to the level of the pipe F, and alsothe return-pipes and drum F I H, and then to supplyheat to the water inthe generator A, and force the water into circulation through the pipesand vessels B G F HI, either by the pumps herein shown or bysteam-pressure, back to said generator A, so that the water shall partwith its steam only within the reservoir or sub-station O, whence saidsteam will be supplied, through distributing-pipes, to the factories ordwellings requiring it for power or heating purposes. What volume thewater loses by the escape of steam from the sub-station 0 is supplied bya feed-pump, L, through the drum H, or directly to the generator A.

It is designed to construct a comparatively large generator A, and toapply the heat to it in the most effective and economical manner, and tomaintain a constant steampressure within the said generator of onehundred pounds, or thereabout, per square inch, and to construct one ormore comparatively small sub-stations or reservoirs 0, having amplesteam-space, however, through the bottom of which the hot water shallflow in its circula- ,tion through the system of pipes .andin which thesteam, or a portion of it, from the watershall escape, therebymaintaining a suflicient steam supply and pressure for the purposes forwhich it is designed.

If the sub-stations be set much higher than the central station, a pumpmay be required to force the water from A to C. If the stations be on alevel, a pump may be required to force the water from (J to A. By usingboth pumps, B G, amorerapid circulation of the water can be set up atany time.

Havingthus described myinvention, I claim as new, and desire to secureby Letters Patent In a steam-supply apparatus for power and heatingpurposes, the combination, with the heating-tank A, of the pipe B, pumpB, steamgenerator 0, having safety valve, and connected withdistributing pipes, the returnpipe F, pump G, drum H, pump L, andreturnpipe I, all arranged substantially as shown and described.
